STOP-COCK BOX.

sPEoIEIcATIoN forming part ef Letters Patent No. 613,652, dated November 1, 1898-.

Application filed March 14, 1898.

To all whom t may concern.:

BOURNE, la citizen of the United States, residing in Vakefield, county of Middlesex, and State of Massachusetts, have invented a new and useful Service-Cock Box, of which the following specification, including the accompanying drawings, bearing letters of reference herein referred to, is a full and exact description.

My invention relates to improvements in service-cock boxes-in other words, to the means or device employed in connection with water-supply distribution to protect and give accessto the stop-cocks that are used underground to let on and shut off the supply of water to and from the consumermy objects being to insure the most convenient accessibility with the operators key to the stop-cock, to protect said cock, to avoid danger of derangement by frost and temperature changes to the cock, and especially to simplify and render the device as inexpensive as possible.

I attain the objects noted by means of the device illustrated and hereinafter more fully described.

Referring to the drawings, Figure 1 is an elevation including the box, a section of the supply-pipe, and the stop-cock; Fig. 2, an elevation showingkey; and Fig. 3 is a corresponding sectional elevation taken at right angles to Fig. 1,the base CZ being omitted. Fig. 4 is an under view of cap ce. Fig. 5 is a side elevation of same and showing lock-nut Z, screw Zt, and pin n. Fig. 6 is a plan without the cap. Fig. 7 is a plan of base CZ and parts of supply-pipe. Fig. 8 is a side elevation of base CZ corresponding to Fig. 1. Fig. 9 is a sectional elevation of same parts as shown in Figs. 7 and 8.

Like letters refer to the same or corresponding parts in all the figures.

The device consists of four main partsviz., the cap a, including the lock-nut Z, its screw Zt, and pin n, the body Z), the lower body c, and the base CZ. Beginning with the base, its construction may be understood by reference to Figs. 1, 9, 8, and 7. This base is a simple casting, requiringno fitting, of pot form, having drainage-opening CZ in the bottom, which also admits the bottom end of cock e. It is provided with slots in the rim, suit-able to receive the service-pipe, which Serial No. 673,841. (No model.)

t slots extend downward from its top and then Be it known that I, EDWARD JAMES CHAD- around the circle horizontally something more than the semidiameter of the servicepipe. These slots are opposed to each other and extend around the circle in one direction. Thus the base-pot may be lifted from beneath the pipe entering the slots and then on being partially rotated locks itself upon the pipe, as seen in Figs. 7 and 8, where it will hang upon l the pipe or may be supported from beneath by illin g under it. After this the lower body c, which is large enough at the lower end to shut over it and is provided with upwardlyextending slots,similar to the downwardly-ex tending ones in the base, is then dropped on, embracing both the base and the pipe f, and on being partially rotated in the opposite direction is thereby locked down upon the pipe, and consequently over and around the base, as seen in Fig. 1.

The locking-slots in the lower body and those in the base extend in opposite directions around the circle as they stand, although, of course, if one were inverted the slots would then be seen to extend around in the same direction. These slots may leave the part overlapping the pipe a little hooking, as may be seen in Figs. 1 and S.

The body b is made larger than the upper portion of the lower body c, so that it slips over it like a sleeve, more or less, according to the depth the pipe is laid from the surface of the ground, pavement, or sidewalk.

The top end of the body has an outer bead or rirn for strength and an inner one having slots, as seen in Fig. 6 and dotted lines Fig. 1. These allow the lock-nut Z, connected to the cap a, to drop through. The inner rim has also the recesses and stop j. (Shown in dotted lines, Fig. 6, and in Fig. 3.)

The cap a has a drooping rim in which are formed the slots on, in which the lock-nut is guided and turned about with the cap a.

A screw 7c has a seat or bearing in a depression in the top of the cap and, passing through the cap, is threaded to fit the locknut, and a pin n through it keeps the nut from accidentally screwing off. The top end of this screw is made in any form to flt and be operated by the operators key.

WVhen it is required to put the cap'on, it is dropped on the inner rim entering the bodytop, the lock-bolt dropping through the slots p, (see Fig. 6,) after which the cap is turned until the lock-nut comes to the stopsj or under the adjacent recesses cc, (see Fig. 3,) when on turning the screw the lock-nut grips the inner rim of the body and the cap is fastened. Vhen it is required to take the cap off, the reverse movement is given the screw until the nut drops clear of the recesses x, when the cap may be turned till the lock-nut comes to slots p and is drawn up through them and the cap lifted. \Vhen the cap is off, the wrench or key g may be passed down to the cock c, and, gripping its plug 7L with its jaws i', the plug is thereby easily turned for letting on or shutting ott the water, and the whole device may also be used in similar cases for gas and other underground stop-cocks.

The part-s may be simple iron castings eX- cept the screw 7e, nut Z, and pin 1t, which are preferably of non-corrosive or nonoxidizable material.

The arrow in Fig. Vindicates the direction the base is turned when locking it to the pipe.

The arrow in Fig. G indicates the direction the screw is turned when locking the cap. It also indicates the direction the lower body is turned when locking it to the pipe and so inclosing the base already locked thereto.

I claiml. In a stop-cock box, a pot-shaped bottom or base constructed with suspending-hooks formed in its sides to engage, and hang upon the pipe at either end of the stop-cock and provided with a central drainage-hole into which the lower end of the stop-cock may protrude substantially as shown and described.

2. The combination of the described potlike base having the suspending-hooks formed in its sides, the horizontal pipe extending in opposite directions from the stop-cock, and an upwardly-extending sleeve or case inclosing said suspended pot and provided with hooks formed in its sides and engaging the hooks operating together upon the pipe to thus inclose and protect the stop-cock and exclude the surrounding earth substantially as shown and described.

4.. In a stop-cock box the top cover having a down wardly-projecting rim to enter the top of the boX, said rim being provided with central vertical slots and also playing in said slots up and down and moved and controlled by them, a horizontal lock-bar screwed at its center upon a screw projecting through the cover and provided with pentagon or-other key-operated head, and a pin below the lockbar to keep said bar from screwing fully 01T and dropping, in combination with the described stops and holding lugs or flanges, substantially as shown and described.

5. The recess x in combination with the cover, lock-bar, stops, holding lugs or flan ges, and screw substantially as shown and described.

6. The stop-cock box having the four sections constructed and operating together as described, viz., the pot or base formed with the suspension-hooks, the lower body inclosing said base with its pipe-hooks, the upper body inclosing said lower body, the cover constructed with the slotted internal downwardly-projecting rim grasping, and controlling the rotary movement of, the lock-bar, said lock-bar, screw, pin, stops and lugs or anges, substantially as shown and described.
